DEVICE FOR SECURING HOSE TO COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 398,582, dated February 26, 1889.

Application filed January 23, 1888. Serial No. 261,629. (No model.)

Boston, in the county of Suffolk and State of l Massachusetts, have invented certain new and '1 useful Improvements in Devices for Securing Hose 'lio Couplings, of which the 'following' is a specification.

This invention has for its object to provide a cheap, simple, and etifective means for ses 1o curing a piece of compressible hose or pipe to the tail-piece of a coupling` or other like j press simultaneously toward the center of the appliance; and it; consists in the combination, with a tailpiec,e and a piece of compressible hose or pipe placed thereon, of a continuous ring of sheet metal surrounding that portion of the hose which incloses the tail-piece, said ring being corrugated or indented at regular E intervals to forni a series of arches, which i compress portions of the hose against the taileo piece, the said arches by their form making,`

the ringI sufficiently strong to maintain its manent the hose-clamping shape imparted to holdingpressure, as I will now proceed to describe.

Of the accoinpanying` drawings, forininga 1 part of this specification, Figure l represents i a longitudinal section of a coupling having a t section of rubber hose secured to one of its tail-pieces by my improvement. Fig. 2 represents a transverse section of the ring, tail- 3o piece, and hose before the ringi is corrugated. 1

Fig. 3 represents a similar section after the ring is corrugated.

The saine letters of reference indicate the saine parts in all the figures.

tail-pieces of an ordinary coupling, (formingno part of nrvinveutiouf) said tail-piece being' externally corrugated, as usual.

b represents a piece of hose of compressi ble i 4o material-such as rubberplaced upon the tail-piece a..

In the drawings, (L represents one of the` c represents a continuous ring' oi' any suitl able sheet metalsuch as copper, brass, or iron. Said rin g, which is originally cylindrical, is placed while in cylindrical forni upon that portion of the hose which incloses the tail-piece, and is of such diameter that it (its somewhat closely on the hose.

When the ring and hose are in place on the tail-piece, the ring` is iorrugated, as shown in Fig. 3, by pressing inwardly different parts of its periphery by means of any suitable appliance, preferably a series of jaws, which ring and thus form a series of inwardly-projecting or inverted arches separated by intermediate outwardlyproject-ing` arches. The ring is thus caused to bind the hose firmly upon the tail-piece, the re-entrant curve or arch of each corrugation compressing the hose, as will be readily seen. The series of inwardly and outwardly proj ec-ting` arches, by virtue of their arched forni, tix or make per the rin g, so that the hose cannot be removed from the tail-piece without cutting the ring.

I claimd The combination, with a tail-piece and a compressible hose or pipe placed t-hereon, ot' a metal ring placed upon that portion of the hose which receives the tail-piece, and corrugated or indented at intervals on the hose to forni a series of inwardly projecting or inverted hose-clamping' arches and int erinediat e outwardly-projecting arches, as set forth.

In testimony whereof I have si gned in v naine to this specification, in the presence of two subscribing witnesses, this `20th day of January, 18%?.
